Kirby vacuum Micro-Matic problem

[ncovert]

Ok, has anyone had this problem before? When you go to adjust your post-1984 Kirby and push the top button, it slips and goes down more than one notch. I have this problem with my Heritage II and my G4. Is there any way to fix this and is this a common problem?

Noah,

Your problem is that the screw in the foot pedal (the Micro-Matic part) may have been adjusted so as to serve lower carpet piles than the standard eight positions. I think you want to back the screw out enough so it won't go lower than the number 1 position.

I tried that, and it still slipped from 8 to the bottom.

Possible cause

I have heard that the ratchet teeth or the receiving part of the ratchet mechanism which is part of the fan case could be worn out.

The Kirby Heritage II service manual says this:

a. "If front bracket shaft (131684S, 131687S or 131688S depending on model) needs service, remove two clamp screws (134157S) from bottom of fan case and allow free end of shaft to fall away from fan case. Ratchet end of shaft can now be lifted away from ratchet lock (133073G) and spring (1331S)."

b. "If ratchet lock mechanism is too stiff or tight, you should disassemble and grease both the ratchet plunger and ratchet gear teeth. Also, repeated operation will break-in assembly for easier use. If you do not have extra ratchet locks in stock, you may try switching from other units to achieve a better match for smooth operation."

c. "To assemble front shaft to motor, hold ratchet plunger lock with spring in place (see figure 16 in manual). Position ratchet as shown and then lower it into place."

Replace the ratchet assembly this will solve that problem.
